khaley, I don't know the exact dimensions of my vanity, but it's under 22 inches. We had a hard time finding something that fit our small space without overwhelming it, so we went with a semi-custom vanity (with choices of size, wood, finish, counter, sink) by Strasser Woodworking at Expo Design Center. It took 2 weeks from ordering to delivery, and we were very happy with the variety of options. I'm fairly certain your 18-inch depth could be accomodated.

Never mind this question! I went to a plumbing showroom and looked at the "real" one in person. Yup, plastic.

Hi francoise47, Yes, I did buy the Wellspring to go along with the Kohler Vinnata. I've been very happy with it. It works well and it's unobtrusive. I bought a different cartridge filter so I can't comment on the Wellspring cartridge but I've been happy with all my Kohler products so it should be fine. Here are a couple of pics of the two faucets together. I'm afraid that it's hard to get the right light for photos in that space but hopefully you can get an idea. FYI, that Vinnata faucet is the larger one. Care

I decided on getting the new Vault, which is also Smart Divide. We wash a lot of dishes by hand, so I need two sides, and I like all the accessories that Kohler has, like the dish drain/rack. I do a lot of cleaning in the kitchen by filling one side with dish soap and clorox, using a dish towel to wipe everything down. Having two bowls lets me do that easier and faster..... ....and having that lower bridge in the middle means if I forget and leave the water on, I won't flood the entire kitchen.... ...not like that has ever happened! LOL
